When trying to load a file via a link, such as https://gefra-lennestadt.com/?gfid=27, nothing happens. The Developer Tools show the error “[HTTP/2 500 Internal Server Error 360ms]”.
If I take the user or file from the authorized group, the correct error message “Forbidden – You don’t have permission to access this resource on this server.” appears.
Downloads that are not protected by Groups File Access work fine. e.g. https://gefra-lennestadt.com/wp-content/uploads/2022/04/Broschüre-GEFRA-Wohn-Flex-Konzept.pdf.
For testing you can register here: https://gefra-lennestadt.com/registrierung/
The login is here: https://gefra-lennestadt.com/login/
The protected downloads are here: https://gefra-lennestadt.com/exposes/
Do you have any advice on how to fix this error?
Thank you very much for your support.
